You probably should investigate how you are getting a lonely " in the first
place.

ESS is using font-lock-warning-face for all those keywords declared in
ess-R-message-prefixes. Unfortunately those are english only. People would need
to enhance those to get a proper highlighting for other languages.

ESS also has regexp based error tracking which are highlighted by compilation
minor mode with links. See ess-R-error-regexp-alist if you want to enhance that.
